By referring to the drawings, it will be seen that I0 designates a circularbase which is provided with an upstanding wall ll having vertically extending vents or slots l2 formed therein for the purpose of admitting air into the base I 0. The base 10 is provided with a sliding drawer l3 which may be slidably mounted in any convenient manner, such for instance as through the medium of the trackway I 4, shown in detail in Figure 6. The drawer I3 is provided with a bottom I5 upon which may rest a tray IE for containing insecticide, perfume, water, or any suitable material or substance. This substance may be in the nature of a liquid, powder, or dust.

A The base l0 may be suitably designed and carries a shut-oil" I! located above the vents or slots I'Z in the nature of a circular plate having vent openings 18 which are adapted to register with vent openings l9 formed in a coacting rotating plate 20, which rotating plate 20 may be actuated by a suitable handle 2| for opening and closing the shut-off, the size of the openings being regulated by the movement of the plate 20 to control 40 the amount of air passing through the shut-off IT. The shut-oil I1 may be varied as to its structural features without departing from the spirit of the invention. -The base I0 is preferably gradually reduced in its circumference as it nears its top to provide a suitable structure which will not have a tendency to topple over.

The base Ill carries near the top thereof and above the shut-off I! a plurality of cross-braces 22 from which is suspended a motor carrying housing 23 in which is mounted an electric motor 24, which electric motor may be controlled by a suitable control switch 25 of the conventional type, such as is used upon electric fans and" the like, in conjunction with a rheostat for providing varied degrees of speed, the various positions being indicated by the numerals l, 2 and 3, and the letters OFF. The housing 23 is suspended below the cross-braces 22 Centrally of the base l8 and extends down through the shut-oi! II, as shown, the shut-off I! also providing a bracing means for the housing intermediate its ends.

The base I8 is provided with an upstanding annular collar 28 within which fits the lower end 21 of the fan shielding dome 28, a set screw 28 being provided upon the annular collar 28 for binding and locking the dome in position. The dome 28 is provided with vertically extending closely arranged vents or slots 38 which extend through a major portion of the height of the dome as shown in the drawings. A suitable bearing 3| is provided at the top of the dome for receiving the upper end of the fan shaft 32,

the fan shaft 32' 'being..c arr ie d by the. motor 24 and having a bearing approximately at the point 33 in the motor 24 and at the point 34, as is common with such motors. It is not desired to limit the present invention to any particular type of motor but it is important that the fan shaft which supports the fan 35 extend in a vertical position centrally of the dome 28, as shown in detail in Figure 3.

The fan 35 preferably comprises three specially constructed fan blades 38 which are arranged at equal distances apart and extend vertically of the shaft 32. Each blade comprises an elongated body having an angularly bent fin 31 bent at a' radical angle along the inclined line 38 which terminates at its upper corner in an angularly bent tongue 39. The lower outer corner of each blade 36 is provided with an oppositely bent tongue 48, as shown in Figure 3. The purpose of this fan 35 is to draw the air up from the base after it enters the vents i2 and into the dome 28, this drawing action being accomplished by the lower portion of the blades 38, and the tongues 40 at the lower ends of the blades, the upper portions and particularly the upper tongues 39 constituting means for driving the air out through the vents 30 in the dome 28, in this way providing an efficient outward radiation of the air from the center outwardly in all directions covering a maximum area.

The upper and lower portions of the fan blade extend substantially at right angles to each other, the lower portion being bent forwardly in the direction of rotation so as to draw the air upwardly longitudinally of the blades of the fan, the blades being elongated vertically and the upper portion of the blade in each instance will force the air from the center outwardly through the vents.

It should be understood that the present device is especially adapted as an air conditioning medium wherein water, insecticide, perfume, or other substance may be inserted in the pan or tray 18. By drawing a blast of air through the vents l2 through the action of the fan 35, a current of air will be drawn across the surface of the contents of the tray l8 and up through the base into the dome 28, and then blown out through the vents 38, in this way humidiiying, perfurning, or disinfecting the air surrounding the fan, the blast of air being broken up into a plurality of' vertically extending streams and radiating from the center outwardly in all directions by being forced out through the vents 38.

As shown in Figure 5. the vents may be, if desired, formed by bending the flanges 4| which are formed by cutting out the vents 42 backwardly to provide substantially V-shaped walls or abutments against which the air which moves radially outward may be forced and then directed out the arrows in Figure 5. It should be understood that the vents may be formed by punching longitudinally extending slots or openings in the dome and base, as shown in detail in Figure 3, or may through the vents 42 in the manner indicated by 5 be formed in the manner shown in Figure 5 in 10 detail, the structure shown in Figure 5 being found preferable and of advantage in many. cases.

In Figure '7, there is shown a modified form of the invention wherein a base 43 is illustrated containing a motor 44 and a compressor or pump 45 15 in conjunction with a vertically arranged conditioning coil 48 which may be utilized as a cooling or as a heating medium without departing from the spirit of the invention. The motor 44 may to" an electrical supply line 41. The vertically arranged conditioning 46 is placed within a vertical column 48 carried by the base 43, which column is provided with vertically extending be connected in any suitable or desired manner 20 closely arranged vents or slots 49 which are,

formed therein in any suitable or desired manner, the cut-out portions being bent back to provide air deflecting flanges 49*, if desired, in a manner shown in Figure 8 similar to that as described in Figure 5. These deflecting flanges 49 may or 3 may not be employed without departing from the spirit of the invention and the slots 48 may be cut out in a manner shown in Figure 7 or the deflecting flanges may be formed from the cut-out portions in the manner as shown in Figure 8, if de- 35 sired.

A removable dome 50 is fitted upon the upper end of the column 48 and may be detachably secured thereto by means of a set screw 5| of a suitable type whereby the dome may be removed 40 when desired for the purpose of repair or replacement. The dome 58 is provided with vertically extending vents or slots 52 extending entirely around the circumference thereof. The dome is supported upon cross-braces 53 somewhat similar to the cross-braces 22 previously described upon which cross-braces is suspended a fan operating motor 54 similar to the motor 24 previously described. The motor 54 is hung within the upper end of the column 48 below the braces 53 and the braces 53 are so constructed as to allow air to pass vertically of the column 48 around the sides of the motor 54 and up into the dome 50 in the path indicated by the arrows. A fan 55 is carried by a vertical shaft 58, the fan being of the same type as that described and indicated by the numeral 35 having vertically extending blades especially formed to suck the air up from the column 48 into the dome 50 and then drive the air out through the vents o'r slots 52. The upper end ment of my invention, illustrating a base 60 supporting a column 6i having air inlet openings or vents 62 The column BI is elongated near its upper end, as at 63, and supports a motor 84 which is hung therein in a manner such as is described and illustrated in Figure '7. A dome 85 is a manual or thermostatic portion 83 of the column 6i and is provided upper end 0! the enlarged with vertically extending apertures or vents 66. A vertically extending fan 61 is mounted within the dome 66 and a light supported upon the It should beunderstood that a very simple fan and housing therefor have been provided for fe cilitating the conditioning of the air and the perfuming and disinfecting thereof, and that. the fan is so'mounted as to not only efflciently distribute the air, but also providing means formight come into close contact therewith. The tray l6 may contain insecticide, dry ice, perfume or any material or substance. If desired, a sponge may be saturated with the desired material over directions. The fan blades will at the same time be shielded to render the fan safe, the open-1 humidifylng, perfuming, fumigatvice might also be utilized for controlling insects and other pests of like nature, by placing an insecticide in the tray, such as is illustrated in the form shown in Figure 3.
